you need a tail rotor. every action there is an equal an opposite reaction

[rctestflight]

@201wrestler no, it already has yaw control

[hhsphotography]

Looking good. Have you considered two motors, with props oriented to they rotate in opposite directions.. to kill the torque effect?

[rctestflight]

ya but i am having no problems with torque roll, the gyro holds it pretty still

[bnrusso]

I also wonder how it would work with 1 gyro for left/ right 1 gyro for front/back and 1 gyro for rotation.

[rctestflight]

It has one gyro for every axis, roll(rotation), yaw(left,right) and pitch(front back)

get rid of the nacelle, you'll get far more lift & stability without it around the propeller.

It appears to be top heavy. You need to move your center of mass down, plus you may also be getting ground effect from your thrust.

[MagicalPonyFromMars]

By all of your videos, I just imagine a little room full of all of your rc builds...lol Do you keep them all?

[Overdosedd1225]

inherently stable in hover or climb. but with when descending it loses the trust keeping it upright like a pendulum and therefore goes into a wobble patter. cool video though

[henshooten]

the circling tells me its top end heavy when decelerating IMHO

[sniperkid90]

@201wrestler Yes but you have to remeber it cannot effect the flight pattern because the tourque is internal and a law of motion is nothing can move unless it is acted upon by a outside force. The motor is inside the aircraft.

[daceknerr]

if you look at military drones that use this configuration youll notice the prop is inside the drum and the inlet is curved out like the leading edge of a wing, this creates extra lift as teh air is sucked in and over the inlet into the barrel. may be something to play with, it will also move your center of pressure slightly higher above your mass. the decent problem i feel is more an turbulent inlet issue than control surface issue. you need nice smooth air from the top for control below...

[Kjetilaf]

if you had removed that barrel around it, maybe it would be easier to control when it is coming down?

[hallobaaaby]

I think it's stable when going up because it has a nice stream of compressed air that supports it--it's actually the only thing that supports it (no wings). So when it's going down, the throttle is weaker, thus the air is less compressed, thus the contraption has less stability support. If to make it go down you could put inside some tubes that would simply simetrically redirect the air sidewise instead of straight down (without cutting on throttle) then it'd prolly go down while staying stable.

That look like a lot of fun. Maybe if you hooked a gyro on to the control vains some how. Or maybe antiservo tabs with counter weights in the controll vains to slow up the pitch over.
